Knowl

Knowl is a persistent memory layer for AI coding agents. It stores typed knowledge atoms — decisions, constraints, architecture, facts, goals, state, and skills — with provenance (observed, stated, inferred). When a fact is superseded (e.g., "rate limit changed from 100 to 500"), the predecessor is retired, not deleted, keeping a full timeline.

The tool runs as an MCP server, so any MCP-compatible client works. Installation is npm install -g @dat999zx/knowl. Knowledge stays local to your repository until you publish; embeddings and session history are never uploaded.

The live site explains the problem of stale knowledge and positions Knowl as a solution that outlives team members. It includes performance benchmarks and a list of supported clients. This is infrastructure for teams that want their agents to remember past decisions.
